The cost to rewire a house Perth homeowners face is one of the biggest questions for anyone
living in an older property. If your home was built before the 1980s, the original wiring may now
be brittle, unsafe and well past its use-by date. Below you will find realistic 2026 prices, the
warning signs to watch for, and seven practical tips to keep the job affordable.
What Is the Average Cost to Rewire a House Perth Homeowners Pay?
In Perth, a full rewire typically ranges from about $6,500 to $20,000 or more, depending on the size, age and access of your home. Smaller units sit at the lower end, while large or two-storey homes climb higher.
Most of the bill is labour, cabling and how hard your wiring is to reach. As a rough 2026 guide:
| Job type | Typical Perth price (2026) |
|---|---|
| 1–2 bedroom unit | $4,000–$6,000 |
| 3 bedroom house | $6,500–$9,000 |
| 4+ bedroom or two-storey | $9,000–$20,000+ |
These are indicative ranges only. Perth’s double-brick construction often makes cable runs slower than timber-framed homes, which can nudge prices up. Always request a written quote before you commit.
Full Rewire vs Partial Rewire
Not every home needs a complete rewire. A partial rewire replaces only the circuits that are unsafe or non-compliant, which is useful when problems are isolated to one area. A full rewire renews all cabling, points, switches and usually the switchboard.
Partial work costs less upfront, but if your wiring is uniformly old, a full rewire is often better long-term value and safer.
7 Warning Signs Your Perth Home Needs Rewiring
- Frequent tripping circuit breakers or blown fuses.
- Flickering or dimming lights when appliances switch on.
- Discoloured power points or a faint burning smell.
- Buzzing or crackling from walls or the switchboard.
- Old cabling such as VIR, rubber or cloth-insulated wires.
- No safety switches (RCDs) on your board — see our switchboard upgrade service for upgrades.
- A fuse-based board and two-pin sockets in a pre-1980s home.
If you notice any of these, book an inspection promptly. Faulty wiring is a leading cause of house fires, and DFES electrical fire safety offers practical home electrical-safety guidance.
Why Older Perth Homes Increase the Cost to Rewire a House Perth
Character and pre-1980s homes often hide asbestos backing boards, deteriorated insulation and difficult roof or subfloor access. Each adds time and care. Double-brick walls, common across Perth, sometimes require surface-mounted conduit where cables cannot be fished through cavities.
How Long Does a Rewire Take and Will You Lose Power?
A typical 3-bedroom Perth home takes three to five days. Power is shut off to sections as work proceeds, so plan around it. Some families choose to stay elsewhere for the noisiest days, especially if working from home.
Do You Need a Compliance Certificate in WA?
Yes. In Western Australia, only a licensed electrical contractor can legally rewire a home, and you should receive an electrical compliance certificate on completion. Most insurers also expect proof the work meets the AS/NZS 3000 Wiring Rules (Standards Australia). Keep this certificate with your home records.
7 Tips to Reduce the Cost to Rewire a House Perth
- Get at least three written quotes from licensed contractors.
- Combine the rewire with a switchboard upgrade service in the same visit.
- Schedule it during renovations, while walls and ceilings are already open.
- Bundle extra power point installation and lighting into the one job.
- Choose quality over the cheapest quote — unusually low prices often mean cut corners.
- Ask whether a partial rewire is enough if only some circuits fail.
- Confirm the compliance certificate and clean-up are included.
